Nickel alloys /ˈnɪkəl ˈælɔɪz/ – nickel-based alloys (Ni). In technology, mainly complex alloyed nickel alloys are used, in which the Ni content (by weight) is about 50% or more. Most nickel alloys are solid solutions containing various elements [chromium (Cr), manganese (Mn), iron (Fe), copper (Cu), aluminum (Al), titanium (Ti), molybdenum (Mo), tungsten (W) , vanadium (V), etc.], have a face-centered cubic lattice.
